Timothy Flynn	8a4ac9c387	LibTimeZone: Add an API to retrieve the system's current time zone ... This is a wrapper API around the POSIX tzset / tzname information. It is to help ensure that tzset is invoked before accessing tzname.	2022-01-12 15:43:12 +01:00
Timothy Flynn	09c0324880	LibTimeZone: Begin generating GMT offset rules for each time zone ... This is a rather naive implementation, but serves as a first pass at determining the GMT offset for a time zone at a particular point in time. This implementation ignores DST (because we are not parsing any RULE entries yet), and ignores any offset patterns of the form "Mon>4" or "lastSun".	2022-01-11 00:36:45 +01:00
